洛芬待因缓释片对癌痛和术后痛的双盲模拟对照研究

目的阿片类与非甾体抗炎药的复方制剂已被广泛用于缓解各类疼痛。可待因作为中枢镇痛药既可单独使用也可与其他非甾体抗炎药联合应用。观察洛芬待因(布洛芬/可待因)缓释片治疗癌痛和手术后疼痛的安全性和有效性。方法采用双盲、双模拟、自身交叉对照法,18例癌痛患者均接受洛芬待因缓释片400/26mg、可待因片30mg、安慰剂3次服药。60例术后疼痛患者随机分为两组,分别接受洛芬待因缓释片400/26mg和可待因片30mg的治疗。结果纳入疗效分析的合格病例共78例,洛芬待因缓释片的临床镇痛效率与可待因片相当,两药无显著性差异(P>0.05),但对于术后疼痛患者洛芬待因缓释片平均镇痛持续时间长于可待因,两药有显著性差异(P<0.05)。试验中未见不良反应发生。结论洛芬待因缓释片治疗癌痛和手术后疼痛的疗效确切,不良反应少。
